Abstract
In the coal mine laneway tunneling through each of the fault fracture zone, the support has been a major technical problem. Because in the near fault, the roof pressure of fractured rock, roadway, or even roof fall accident, bring safe hidden trouble for the drivage. According to field 2210 Lane fault situ ation, adjust the bolt, anchor cable supporting parameters, give full play to the anchor, active supporting effect, and according to the observation of the top floor displacement, abscission layer quantity and anchoring force, prove the supporting scheme is feasible.关键词
